Ozone - Wikipedia

Ozone (/ ˈ oʊ z oʊ n /), or trioxygen, is an inorganic molecule with the chemical formula O is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down in the lower atmosphere to O 2 ().Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the ...

DETERMINATION OF OZONE BY ULTRAVIOLET ANALYSIS

The detection limit for ozone is ppm (Code of Federal Regulations, Volume 40, Part , or, in the shortened format used hereafter, 40 CFR ). For reference, the ozone standard in 1996 is ppm, averaged over 1-hour intervals, to be exceeded no more than once per year (40 CFR ). Format and Purpose The sequence of topics covered in this ozone by UV method is different ...

Ozone-Depleting Substances | US EPA

· The ODP is the ratio of the impact on ozone of a chemical compared to the impact of a similar mass of CFC-11. Thus, the ODP of CFC-11 is defined to be Other CFCs and HCFCs have ODPs that range from to The halons have ODPs ranging up to 10. Carbon tetrachloride has an ODP of , and methyl chloroform's ODP is

Ozone Concentration and Dosage Equations

20 gpm x l/gal x 60 min/hr. x 2 ppm = 9084 mg/hr. ( gm/hr.) Remember that 9 mg/hr. will permit you to dose the water with 2 ppm of ozone. This does not mean that 2 ppm will be your final dissolved ozone concentration. Due to efficiency losses with injecting ozone and ozone demand of the water, your dissolved ozone concentration will be less.

Ozone - NASA

Ozone. In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O 2 ), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone.

Methods of Low-Temperature Sterilization: Ozone | Tuttnauer

An ozone sterilizer is able to harness the unique powers of ozone by producing it inside the sterilizer from medical grade oxygen, which is commonly available in hospitals (as explained above, by applying electrical energy to combine O2 with O to form O3). This capability is well-suited for sterilizing delicate medical devices, like endoscopes, that cannot withstand the high heat and humidity ...

Ozone Detection Crucial to Climate Change | News | Envin ...

· Ozone detection will be essential in the years ahead, as climate change means pollution levels of the gas are likely to rise substantially. Ozone pollution is a sunlight-driven process The National Center for Atmospheric Research in Boulder, Colorado, has published research showing that summertime ozone levels in the US are likely to increase by as much as 70% by 2050.

NASA - Discovering the Ozone Hole: Q&A With Pawan Bhartia

Ozone was a hot topic among scientists an August 1985 meeting in Salzburg, Austria, a few days after Pawan Bhartia presented the first satellite image of the ozone hole. In attendance were Donald Heath, who initiated the ozone measurement program at Goddard in the late 1960s, and the late Sherry Rowland, who later received the Noble Prize for ozone layer research.

Ozone Chemistry - NASA Advanced Supercomputing Division

Hydrogen fluoride, HF, is so very stable that fluorocarbons have relatively no known impact on ozone. Bromine resevoirs, such as HBr and BrONO2, are much more easily broken up by sunlight ; causing bromine to be from 10 to 100 times more effective than chlorine at destroying ozone. From 30-60% of bromocarbons released to the atmosphere are man-made (methyl bromide fumigants and halon fire …
